NBN Co accused of duplicating existing internet services

THE company charged with rolling out the National Broadband Network (NBN) has been accused of wasting taxpayers' money by installing exactly the same internet services on top of existing broadband in some areas.

Michael Sparksman, the chief executive of OPENetworks, told Lateline that two years after his company installed a superfast broadband network in a building in Sydney Park Village, NBN Co installed the same service.

"It's exactly the same as building two super freeways to a community," he said.

"They provide the same services and facilities over which the trains and trucks and cars can travel and so there is no benefit in having duplication of that infrastructure."
